Oceanography

Aquadopp 6000 m

Courantomètre ponctuel grands fonds conçu pour les longs déploiements avec corps en titane

Aperçu

With all the features and capabilities of the standard Aquadopp, the deepwater Aquadopp 6000 m current meter has been used and proven by oceanographers around the world for almost 20 years. Thanks to innovative data diagnostic features for challenging environments, it provides exceptionally high-quality 3D currents in a form factor that is easy to install in any type of mooring line configuration, or simply attached to a bottom or surface platform.

Raw magnetometer data can be stored for post calibration of compass when used without the inductive modem option.

  • Currents

Points forts

  • Full ocean-depth single-point current meter
  • Titanium housing
  • Diagnostics mode for mooring performance evaluation

Utilisation

  • Studies of deep-water currents
  • Studies of tidal currents
  • Attached to mooring lines
  • Measurements of unaffected currents from physical structures
  • In conjunction with riser monitoring systems
  • Alternative to conventional current meters with errors due to fouling
  • Combination of currents and high-accuracy CTD data
  • Near-bed current measurements from landers
  • Deep ocean mining support

Setup

Nortek deployment software allows users to customize their 600m Aquadopp deployment in a straightforward manner, providing guidance on deployment schemes, battery power and required internal memory.

Deployment

The 6000m Aquadopp is the ideal current meter for deep-water moorings with a designated mooring-specific head design available. The instrument is capable of very long-term, unsupported deployments thanks to its low power consumption, internal data collection and ability to run entirely on internal battery power.

Data

Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
